Important: Limitations of Automated Scanning
A perfect security score (100) does not mean your systems are fully protected. This automated scan detects common vulnerabilities but cannot identify all security risks. Results may contain false positives or miss certain vulnerabilities. Always verify findings manually and implement additional security measures.
Treat this report as a starting point, not a complete security assessment. Engage security professionals for comprehensive penetration testing and security audits.
Beyond This Scan: Critical Security Areas Not Covered
This automated scanner focuses on infrastructure vulnerabilities, exposed services, and configuration issues. However, many critical security threats require manual testing, code review, or specialized tools. Ensure your security strategy addresses the following areas:
Application Layer Attacks
- SQL Injection: Validate and sanitize all database inputs. Use parameterized queries/prepared statements.
- Cross-Site Scripting (XSS): Sanitize user inputs and encode outputs. Implement Content Security Policy.
- Input Validation: Validate all form inputs server-side. Never trust client-side validation alone.
- Authentication Flaws: Implement MFA, secure password policies, and proper session management.
Infrastructure Attacks
- DDoS Protection: Implement rate limiting, CDN with DDoS protection, and traffic filtering.
- Brute Force Prevention: Add account lockout policies, CAPTCHA, and login attempt monitoring.
- Path Traversal: Validate file paths, use chroot jails, and restrict directory access in web server config.
- Server Misconfiguration: Disable directory listing, remove banners and default pages, and restrict file permissions.
Advanced & Emerging Threats
- 0-Day Vulnerabilities: These are unknown vulnerabilities that automated scanners cannot detect. Maintain defense-in-depth strategy.
- Supply Chain Attacks: Audit third-party dependencies, use Software Composition Analysis (SCA) tools.
- API Security: Implement proper authentication, rate limiting, and input validation for all APIs.
- Social Engineering: Train staff on phishing, pretexting, and other manipulation tactics.
Data & Business Logic
- Data Encryption: Encrypt sensitive data at rest and in transit. Use strong encryption algorithms (AES-256).
- Access Control: Implement principle of least privilege. Review permissions regularly.
- Business Logic Flaws: Test for race conditions, price manipulation, and workflow bypasses.
- Backup Security: Encrypt backups, test restoration procedures, and store off-site securely.
Malware & Virus Protection
- Endpoint Protection: Deploy enterprise-grade antivirus/anti-malware on all devices (servers, workstations, mobile). Consumer AV is insufficient for business.
- Real-Time Scanning: Enable continuous monitoring and automatic updates. Malware signatures become outdated within hours.
- Email Security: Implement email filtering and sandboxing. 94% of malware is delivered via email attachments or links.
- Web Filtering: Block access to known malicious domains and prevent drive-by downloads from compromised websites.
- EDR/XDR Solutions: Go beyond traditional AV with Endpoint/Extended Detection and Response for behavioral analysis and threat hunting.
- Regular Scans: Schedule full system scans weekly. Don’t rely solely on real-time protection.
Antivirus is NOT optional. Even with perfect network security, one infected USB drive, malicious email attachment, or compromised website can introduce malware. Modern threats include trojans, keyloggers, spyware, cryptominers, and fileless malware that traditional scanners miss.
Asset Management & Rogue Infrastructure
- Server Inventory: Maintain complete asset inventory of all servers (physical, virtual, cloud). Include IP addresses, purposes, owners, and last patched dates.
- Forgotten Servers: Regularly scan your network for unknown or forgotten servers. These become prime targets – unpatched, unmonitored, and exploitable.
- Shadow IT Detection: Identify unauthorized servers, cloud services, or applications deployed without IT approval. They bypass security controls.
- Decommissioning Process: Properly shut down and remove old servers. Forgotten dev/test servers often remain accessible with default credentials.
- Certificate Tracking: Monitor all SSL certificates across infrastructure. Expired certs on forgotten servers expose vulnerabilities.
- Network Mapping: Quarterly network scans to discover all active devices. Compare against known asset inventory.
A developer spins up a test server, forgets about it after project ends. Server runs outdated software with default passwords. Attackers find it, use it as entry point to internal network. This happens more often than you think.
Domain Monitoring & Brand Protection
- Domain Portfolio Management: Track ALL domains your organization owns across all TLDs. Include expiration dates, registrars, and DNS providers.
- Typosquatting Detection: Monitor for domains similar to yours (e.g., company-name.com vs companyname.com, c0mpany.com). Attackers use these for phishing.
- TLD Variations: Register critical variations (.com, .net, .org, .co, country-specific) to prevent domain squatting and brand abuse.
- Lookalike Domains: Watch for domains using similar words, different TLDs, or internationalized characters that visually mimic your brand.
- Phishing Monitoring: Use services to detect phishing sites impersonating your brand. Report and take down quickly.
- Auto-Renewal: Enable auto-renewal on all critical domains. Expired domains can be bought by cybercriminals or competitors.
- DNS Security: Enable DNSSEC, registry lock, and two-factor authentication on domain registrar accounts.
Attackers register domains like “yourcompany-secure.com” or “yourcompany-login.com” for phishing campaigns. Your customers receive emails from these lookalike domains and enter credentials. Monitor tools: DomainTools, DNSTwist, or manual searches.
Network Devices & Peripherals
- Device Inventory: Document ALL network-connected devices: printers, scanners, IP cameras, HVAC controllers, door access systems, smart TVs, VoIP phones.
- Firmware Updates: Regularly update firmware on routers, switches, access points, and peripherals. These often contain critical security patches.
- Default Credentials: NEVER leave default usernames/passwords (admin/admin, admin/password). Change immediately on deployment.
- Printer Security: Printers store documents, have web interfaces, and can be entry points. Update firmware, disable unnecessary services, use authentication.
- IoT Devices: Security cameras, smart thermostats, and other IoT devices are frequent attack targets. Segment them from main network.
- Network Segmentation: Place peripherals on separate VLANs isolated from critical business systems. Limit communication to necessary ports only.
- Access Control: Restrict administrative access to network devices. Use strong passwords and disable remote management if not needed.
- Monitoring & Logging: Enable logging on routers/switches. Monitor for unusual traffic patterns or unauthorized configuration changes.
Network printers running outdated firmware are often exploited to access internal networks. One casino was breached through a connected fish tank thermometer. Old routers with unpatched vulnerabilities provide persistent backdoor access. These “insignificant” devices are prime targets because they’re rarely monitored or updated.
Recommended Security Actions
Install enterprise endpoint protection on all devices. Consider EDR solutions like CrowdStrike, Microsoft Defender for Endpoint, or SentinelOne.
Use secure DNS services: Quad9 (9.9.9.9), Cloudflare for Families (1.1.1.3), Cisco Umbrella, or CleanBrowsing to block malicious domains.
Hire security professionals to conduct thorough penetration tests quarterly.
Conduct static and dynamic application security testing (SAST/DAST).
Implement SIEM, IDS/IPS, and continuous security monitoring.
Develop and regularly test your incident response and disaster recovery plans.
Provide regular security awareness training for all employees.
Regular audits for GDPR, PCI-DSS, HIPAA, or other applicable standards.

Ransomware Protection & Business Continuity
No security scan can prevent ransomware. Your survival depends on preparation.
⚠️ CRITICAL REALITY CHECK: Ransomware attacks are not “if” but “when.”
Even with perfect security scores, attackers find ways in through phishing, compromised credentials, or zero-day exploits.
The only guaranteed defense is having tested, immutable backups and a solid recovery plan.
Immutable Backups
Your last line of defense. Without these, ransomware wins.
- Immutable storage: Use write-once-read-many (WORM) or object lock features that prevent deletion or encryption for 30-90 days
- Air-gapped backups: Keep offline copies disconnected from network that ransomware cannot reach
- 3-2-1 Rule: 3 copies, 2 different media types, 1 off-site
- Test monthly: Verify backup integrity and practice restoration procedures
- Version retention: Keep multiple backup versions (14-30 days) in case ransomware sits dormant
Ransomware encrypts or deletes your backups before encrypting production systems. You have no recovery option except paying ransom (which often fails anyway).
Recovery Plans & Keys
Backups are useless without the ability to restore them.
- Document everything: Step-by-step restoration procedures for each system. Don’t rely on memory during crisis
- Encryption key management: Store backup encryption keys in secure, separate location (password manager, HSM, or physical safe)
- Access credentials: Maintain offline copies of all system passwords, API keys, and access credentials needed for restore
- Recovery priorities: Define which systems to restore first (RTO/RPO for each service)
- Quarterly testing: Practice full restore procedures. Time them. Find gaps before disaster strikes
Organizations discover their backup encryption keys were stored on encrypted servers, or documentation was outdated. Result: Backups exist but are inaccessible.
Business Continuity
Keep business running during and after an attack.
- Incident response plan: Pre-defined steps for detection, containment, eradication, and recovery
- Communication plan: Who to notify (leadership, customers, authorities), when, and how
- Alternative operations: Manual processes or backup systems to maintain critical services
- Legal & insurance: Cyber insurance policy, legal counsel contacts, regulatory reporting requirements
- Vendor contacts: List of security vendors, forensics teams, and crisis management firms
Average ransomware downtime: 21 days. Average cost including ransom, lost revenue, and recovery: $4.54M. Good planning reduces both dramatically.
